CHURN.

SPECIFICATION forming part of Letters Patent No. 560,528, dated May 19,1896./

Application filed June 7,1895. Serial No. 5521016. (No model.)

To all whom t may concern:

Be it known that I, HENRY OBERMEYER, of Beatrice, in the county of Gageand State of Nebraska, have invented a new and useful Improvement inChurns, of which the following is a full, clear, and exact description.

My invention relates to an improvement in churns; and the obj ect of theinvention is to provide a churn of exceedingly simple, durable, andeconomic construction, and one wherein a vertically-reciprocating dashwill be employed, the dash being provided with valves closing on itsdownstroke; and a further object of the invention is to provide withinthe churn an agitating-compartment, from which the liquid will be forcedand by means of which the butter when it is made will be assembled uponthe upper face of the dash, thereby enabling it to be readily removed.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improved churn. Fig. 2 is a verticalsection through the same, taken practically on the line 2 2 of Fig. 3.Fig. 3 is a plan view of the churn, and Fig. 4 is an inner face view ofthe wall of the agitating-compartment detached from the body of thechurn.

In carrying out the invention the body A of the churn is of box-likeconstruction, being of any desired dimensions. Usually it is rectangularin general contour and is supported by legs 10, being provided at itsbottom with a faucet 11 for drawing the milk therefrom, and within thesaid bodyT at one side an agitating-compartment B is constructed, andthe said compartment consists of a vertical wall 12, adapted to extendfrom one side of the churn-body to the other, having strips or ribs 13upon its inner face arranged to form, substantially, a series of diamondor baffle partitions forming the lside walls of a series of intersectingchannels, as shown in Fig. 4, and at the top of this wall a horizontalflange 14 is constructed, which is adapted for engagement with the innerwall of the body of the churn, as shown in Fig. 2, while at the top,preferably at each side of the center of the said wall 12, openings 15are made, which communicate with the spaces or channels between the ribs13 of the said wall, and corresponding openings 16 are produced in thebottom portion of this wall, being at the oor of the body of the churn.A cover 17 is fitted on the top of the body, being removable therefrom,and within the said body a dash C is held to reciprocate, being looselyfitted to the walls of the body, as shown best in Fig. 2. This dash isprovided with two or more openings 1S, fitted each with avalve 19, thevalves closing on the downstroke of the dash and opening on-theupstroke. The dash is provided with a stem 20, whichris carried uploosely through an opening in the cover 17 and through a cross-bar 21,the said crossbar being a predetermined distance above the cover of thebody, and it is secured at each end to a pitman 22. These pitmen extenddownward, one at each side of the body of the churn, and are enlarged attheir lower ends, the enlarged portions having longitudinal openings 23made therein, the upper and lower walls of the openings being circularor concaved, and in the entire wall of each opening teeth 24 areconstructed, while at one side of the enlarged portion of the pitmenupon their inner faces a vertical rib or flange 25 is built, the saidflange or rib being near one side edge of each pitman, as best shown inFigs. 1 and'3.

Friction-rollers 26 are made to engage with the anges 25 of the pitmen,and the said iianges are of less length than the slots or openings inthe pitmen. A shaft 27 is journaled, preferably, upon the bottom of thechurn-body, extending from side to side, and the saidshaft is providedat each end with a pinion 28,V the pinions being in mesh with the teeth24 in the pitmen, and the shaft at one end is further provided with anattached gear 29, meshing with a gear 30, secured upon a short shaft 31,located at one side of the churn, and this shaft is rotated by means ofa crankn arm 32 or the equivalent'thereof.

In the operation of this churn, by turning the crank 32 the pinions willtravel in the teeth of the pitmen-slots 23, making the circuit of saidslots, and consequently the pit- IOO men have a side movement as well asa vertical movement when the teeth of the pinions are traveling in theteeth at the ends of the said openings 23, and since the flanges 25 areof less length than the openings 23 the flanges will pass thefriction-rollers 2G both at the extreme upstrolie of the pitmen andlikewise at the termination of the downstroke, the friction-rollersengaging alternately with opposite sides of the ilanges, serving toguide the pitmen in their vertical movement. Under this construction itis evident that a continuous vertioally-reciprocating movement isimparted to the dash, and that but little exertion will be required tooperate the churn. On the downstroke of the dash the liquid will beforced through the agitating compartment or chamber B, and when thebutter comes at the said downstroke of the dash it will be forced withthe milk out through the upper openings 15 in the agitating-compartmentand will form on the dash, accumulating thereon, while the milk willpass down through the valved openings on the upstroke of the dash, atwhich time these valves are opened.

It is evident that the actuating mechanism, herein set forth isapplicable to various forms of machines and need not necessarily berestricted to a churn.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A churn provided with a vertically-1'c ciprocatingdash, and an agitating-compartment formed Within the body of the churn,having ba file-partitions forming the side walls of a series ofintersecting channels and upper and lower openings communicating withsaid channels, substantially as set forth.

2. A churn the body of which is provided with an agitating-compartmentextending practically from side to side and from top to bottom of thebody, the said agitatingcompartment being provided withbaille-partitions upon its inner face forming the side Walls of a seriesof intersecting channels, and upper and lower openings communicatingwith said channels, a dash held to vertically reciprocate within thesaid body, provided with valves closing on the downstroke of the dash,and means, substantially as shown and described, for imparting verticalmovement to the dash by exteriorly-located mechanism, as and for thepurpose specified.
